Describe the bug

When click on record, the first time, it throws me a error, and does not record, but if i close the screen and do it a second time it works.

To Reproduce

here are some code snippets to reproduce

final flutterSoundRecorder = FlutterSoundRecorder();

/// Somewhere in a button 
                    FormButton(
                        label: Text(
                          'Record Audio',
                        ),
                        onPressed: () async {
                          await flutterSoundRecorder.openAudioSession(
                            focus: AudioFocus.requestFocusAndDuckOthers,
                          );
                          await flutterSoundRecorder.startRecorder(
                            toFile: track.trackPath,
                            codec: track.codec
                          );
                          flutterSoundRecorder
                              .dispositionStream()
                              .listen((event) {
                            recordDuration.value = event.duration;
                          });
                        },
                        icon: Icon(Icons.mic),
                      )

I can confirm the audio permissions were already given

That should be fixed with my pull request #677

[Yash-Aervadiya]

Hey @satyajitghana, i am facing the exact error in version 8.1.4. can you share how you resolve the issue ?!

[satyajitghana]

@Yash-Aervadiya

  Future<String> getTempAudioFile() async {
    var uuid = Uuid();
    String path;
    var tmpDir = await getTemporaryDirectory();
    path = '${join(tmpDir.path, uuid.v4())}.m4a';
    var parent = dirname(path);
    Directory(parent).createSync(recursive: true);

    return path;
  }

  Future<void> resetAudioTrack() async {
    String path = await getTempAudioFile();
    recordingFile = path;
    track = Track(trackPath: recordingFile, codec: Codec.aacMP4);
    // setState(() {});
  }

and then on the record button you do something like this

       FormButton(
                        label: Text(
                          'Record Audio',
                        ),
                        onPressed: () async {
                          /// just to be extra safe
                          await resetAudioTrack();

                          await flutterSoundRecorder.openAudioSession(
                            focus: AudioFocus.requestFocusAndDuckOthers,
                          );
                          await flutterSoundRecorder.startRecorder(
                            toFile: track.trackPath,
                            codec: track.codec
                          );
                          flutterSoundRecorder
                              .dispositionStream()
                              .listen((event) {
                            recordDuration.value = event.duration;
                          });
                        },
                        icon: Icon(Icons.mic),
                      )

and this is the stop button

    FormButton(
                        label: Text(
                          'Stop',
                        ),
                        onPressed: () async {
                          await flutterSoundRecorder.stopRecorder();
                          await flutterSoundRecorder.closeAudioSession();

I'm not sure why, but this works for me. I still get some memory leaks, but that is something that many other things could have caused.
